Delta Hydrofoil Pro Tip: How to measure angle of attack on a hydrofoil 

Thank you for share your knowledge! You explanation was super clear. I have an RRD85 foil and it's super lifty. has an 85cm mast, 120 boom, 80 wing and 38 stab (plus another 55 stab purchased separately). I put a stainless steel washer in the front screw of the stab to make a trim correction

5 inches in front of the front screw of the front wing, or of the mast?

does it make a difference when the stabillizer is mounted on top of the fuselage!?

hi what accelerometer chip is inside Wixey WR300? the most of smartphone accelerometers for angle counting has Linear acceleration sensitivity = 0,061

thaks for sharing, only one question if you are so kind of reply. where in the horizontal length of the wing you measure.? (half way from fuselage to end of the wing?

There's a couple videos of guys doing flatwater pumping on a foil board, once they get some speed (boat or paddle) they're foilborne and pumping to keep self propelled for a couple hundred yards. What kind of design and angle do you think would work best for something like that?

Dear Alden what you suggest for stand up paddle? What wing and stabilizer size? Regards Marcelo

I would like to contact you and ask you a question. Do you know how I can do that through RU-vid?

If the fuselage goes horizontally through the water! What is the angle at which the main wing goes through the water ??

Very helpful. But I'm wondering what screw you're referring to when you say the center of your stance should be 5" in front of the front screw? Is this the screw that mounts the mast to the board, the fuselage to the mast, or the front foil to the fuselage? Thanks.

Hi George, thanks for the informative video. If setting up a surf or SUP foil I would presume the stabiliser angle would be less as the nose of the board is not driven down as in a kite board?
